Lisbon’s new riverside architectural icon, designed by London-based studio AL_A, opened last week to a flood of visitors.

After a construction period of two years and an investment of $22 million, the white-tiled, curvilinear kunsthalle, the second building of the new Museum of Art, Architecture and Technology (MAAT), opened its doors to the public on October 5, honoring the national holiday that signals the establishment of the Portuguese Republic.
